What this workflow does
Extras on Buy Me a Coffee are things you sell to supporters: a download, a session, a small product. The buyer's email stays inside Buy Me a Coffee unless you copy it out. This workflow sends each buyer to Acumbamail so you can reach them with your newsletters later.
The Buy Me a Coffee trigger fires when an extras purchase webhook is received. FlowMattic passes the purchase data to Acumbamail, where Add/Update Subscriber adds the buyer to the list you choose. If they're already on it, the same action updates their record.
Because it's an add-or-update action, a supporter who buys several extras stays one subscriber. Each purchase still runs the update, and a blank value in a later purchase can replace a field you had, so map only fields every purchase includes. Task History shows each run and Acumbamail's reply.

After importing, map your own data. To keep the template universal, not every step is pre-filled. Open each step in the builder and connect your accounts and fields (channels, lists, sheets, recipients) before you switch the workflow on.
Make it yours
Changes worth making after you import it.
- Use a separate Acumbamail list for extras buyers, so your newsletter to supporters and your offers to buyers stay apart.
- Make sure your emails to these buyers follow your own consent rules, and add a Filter after the trigger if only some extras should add people to the list.
- Buy a low-priced extra yourself after import so FlowMattic captures a real purchase, then finish the Acumbamail mapping from it.
Questions about this workflow
Does a repeat Buy Me a Coffee buyer get added to Acumbamail twice?
No. Add/Update Subscriber updates an existing subscriber instead of creating a second one. The step still runs for every purchase, so it can change the stored details.
Do coffee donations and memberships trigger this workflow too?
No. The trigger is Extras purchased, which fires for purchases of your extras. Donations and memberships need their own Buy Me a Coffee triggers.
Are past Buy Me a Coffee extras buyers imported into Acumbamail?
No. Only purchases made after the workflow is on reach Acumbamail. Export earlier buyers from Buy Me a Coffee if you want them on the list.
